Engineering Worksheet: Prototypes and Fair Tests

Engineering lesson 5: Prototypes and fair tests · Set 696 · 40 questions

Engineer's tip (Test fairly, record honestly): Prototype = an early model made to test an idea. Fair test: change one thing, keep the rest the same, measure and record every result. Mean of three tests = (first + second + third) ÷ 3.

2. 2.🔍 Which is the odd one out? (a) use a new load each time (b) change lots at once (c) change only one thing (d) skip writing results
3. 3.🔍 Which is the odd one out? (a) skip writing results (b) use a new load each time (c) test it only once (d) measure the same way

21. 21.🔍 Which is the odd one out? (a) repeat each test (b) record every result (c) measure the same way (d) change lots at once
22. 22.🧪 Why do engineers make prototypes? (a) to decorate a room (b) to sell them at once (c) to avoid testing (d) to test ideas cheaply
